Well, I believe I almost have control of this EWOO phenomena. Last night I tried again and got ALMOST the same results. The first two verges, I got a little cum. Then on verge #3, I got the flow. But it wasn't like the night before where it felt like the floodgates completely opened... the flow duration and quantity was about 1/3 my previous attempt, but it was nice thick cum. After drinking that down, I tried a fourth time to see if I could get any more... but even though I got there, very little cum came that time. I guess I was all cummed out lol.
I have another theory on why both orgasm AND ejaculation are necessary to trigger the chemical reactions that cause the refractory period. During a normal orgasm/ejaculation (see quote below), sperm is propelled from the epididymis (attached to the testicles), then mixes with fluid from the prostate and seminal vesicles. I'm thinking that if an orgasm (and the resulting contractions) doesn't take place, the sperm from the epididymis never gets released. And with the reverse (orgasm without ejaculation) then obviously there is no sperm released. Maybe the release of sperm from the epididymis is what triggers the refractory down time. One reason I believe there is no sperm is because my cum didn't taste as bad as I expected. I'm thinking sperm is what makes it really, really bitter-tasting. (My cum also doesn't taste as bad when ejaculating via a PIO (prostate-initiated orgasm), so maybe no sperm with that either?) Since I'm thinking the cum is sperm-less, I guess I could use a powerful microscope to examine my semen for sperm to test this theory lol.
From
http://en.wikipedia.org/wiki/EjaculationDuring emission, the two ducts known as vas deferens contract to propel sperm from the epididymis where it was stored up to the ampullae at the top end of the vas deferens. The beginning of emission is typically experienced as a "point of no return," also known as point of ejaculatory inevitability. The sperm then passes through the ejaculatory ducts and is mixed with fluids from the seminal vesicles, the prostate, and the bulbourethral glands to form the semen, or ejaculate.
I'd like to document this whole thing on video to have a permanent memory/record of it. If I've got the will to go to all the trouble, I might try that tomorrow. One things for sure... with the separation of orgasm and ejaculation, it sometimes makes it difficult to know how to categorize and count things in my orgasm database lol.
